SPINNENG- MACHIN.

SPECIFICATION forming part of Letters Patent No. 381,567, dated April 24, 1888.

Application tiled August '26, 1587. Serial No.2r1'h930. (No model.)

To @ZZ whom it may concern.:

Be it known that 1, JAMES MAnJenrsoN, of Lawrence, county of Essex,and State of Massa` chusetts, have invented an Improvement in Spinning-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention is an improvement on that described and shown in my application, Serial No. 192,057, iled February 15, 1886, to which reference may be had, the object of my invention being to adapt the machine therein described to cap rather than to flier spinning.

To effect this improvement in my said machine, l have added an additional set of clamps and arms to operate them, whereby the said clamps, when full bobbins are to be doffed from the spindles, are made to move upward and forward to grasp the caps, remove them from the upper ends of the deadspindles, and hold the said caps until the full bobbins are removed from and empty bobbins are supplied to the spindles in their place.

I have also provided novel means for connecting the bobbiu carrying tube with a sleeve, which is made vertically movable within the whirl used to rotate the said sleeve. l have also provided means for oiling the bearings in which the whirl rotates.

Figure 1 in front elevation shows a snftlcient portion of a cap spinning frame, which, taken in connection with my application referred to, will enable one conversant with the art of spinning to understand my invention; Fig. 2, a section thercofin the line fr, Fig. 1. Fig. 2 is an enlarged sectional detail showing the oil-cup 23, which receives in it an annular projection from the lower side of the head 24 of the sleeve; Fig. 3, a detail showing the lower end of the bohbin and the top of the head of the sleeve. Figs. 4t to 8 represent details sh ow. ing the positions of the parts at different stages ofthe'dofling operation, and Fig. 9 is a side elevation of the parts shown in Fig. 3.

In this my improved machine the apparatus for applying and removing the empty and full bobbins is substantially the same as iu my said application, except that I have elongated the upper arms of the rock-shaft for moving the clamps that control the empty bohbins and shortened the arms of the rock-shaft having the clamps for the full bohbins, as I find it more convenient in this present case to have the full bobbin-controlling clamps.

In the details Figs. d to 8 I have omitted some of the parts shown in Figs. 1 and 2 and common to my said application, the said detail figures being chiefly to represent the different relative positions ot the. full and empty bobbins and caps at different stages of the dofng operation. ln this present invention the collar-rail has attached to it or depending from it a series of yokelike supports, which act not only as guides for the tubes, to be referred to, out also serve to support the lower ends of the dead-spindle. Herein l have done away with the necessity of raising and lowering the step-rail, as in my application referred to.

The framework A, the cross-beam A', the rail A, the collar-rail A3, secured to it by screws A5, the builder-rail cl2, its lifting-rods d, the lugs or ears 13, the chain e, drum e', buildershaft el, the duiding-shaft b5, its gear c3, the toothed rod or rack e", engaged by it7 the guides el therefor, the rock-shaft e", carried in the bearings or boxes at the upper ends of the rack e4, the hand wheel or pulley bw, to move the (letting-shaftb, the arms f, having studs f', the rail g, the empty bobhin-clamp g* thereon, the rail It, and the full bobbin clamp or jaws it are all substantially as' in my said application, Serial No. 192,057, iiled February 15, 1886, with the exception of slight material differences in the shape ofthe clamps orjaws referred to, and in the fact that thejawsg" are herein shown as made to occupy a position above the clamps or jaws It, such eltnge necessitating only slight alterations in the length ofthe arms supporting the said rails and their Jaws.

Herein the eollar=rail A3 has a depending yolieshaped portion, A, a part of which serves as a steadying-hearing for the sleeve 25, surrounding the dead-spindle B3, while another part receives the foot of the said dead-spindle, it being held in place by a set-screw, 2 0, the vertical position of the dead-spindle being se- Fig. 2.)

the empty bobbincontrolling clamps above cured by means of an adj Listing-screw, 22. (See ICQ Herein the liftingrail cl2 is arranged above the whirls b', and resting upon the top of the said lifting-rail and about each spindle is an oil-cup, 23, (shown separately in Fig. 2,) the said oil-cup having an annular chamber, 23X, to receive snugly an annular projection, 24X, at the under side of the head 24 of the bobbincarrying sleeve 25, the said projection running in the oil in the said annular-groove as the sleeve is rotated. This sleeve 25 is extended down through the raised center of the oilcup,

through the lifting-rail, the sleeve-whirl, and the bearing 26, and the weight of the sleeve is supported by the lifting-rail. The sleeve 25 is slotted at one side to receive in it a key, 27, (see Fig. 2,) extended through the upper end of the whirl b' above the upper bearing of the collar-rail A3, the rotation of the whirl thus rotating the sleeve and head 24 in unison with it, the said slot in the sleeve permitting the latter to be raised by the builder-rail d2 at the same time that the whirl is rotating the sleeve. The head 24 (see Figs. 3 and 9) has at its upper side a slot shaped as shown at 28, and below its top the head is cut away, leaving an open space, as 29, the said slot and space being for the reception of the foot 30 of the bobbin-driving tube 31, the said foot, as herein shown, having two projections or ears and being in cross-section of substantially the same shape as the slot 28. When the foot passes down into the slotso that the head of the bobbin-driving tube rests upon the top of the head 24, the said lugs, by the partial rotation of the bobbin-driving tube, will be caught under the upper flange of the said head in the space 29, thus locking the bobbin-driving tube in position with relation to the head and sleeve 25, so that the bobbin-driving tube' partakes of the motion given to the sleeve, thus causing thesaid bobbin-driving tube to not only rotate, but rise and fall upon the dead-spindle B3. The head 24 of the bobbin-driving tube has a pin, 32,which enters in usual manner a space in the head of the bobbin di, causing the bobbin to be rotated with it.

The upper end of the deadspindle B is tapered in usual form to receive upon it a metal cap, as 33, the said cap being of usualshapesuch as commonly employed in cap-spinning.

frames--the .cap remaining stationary while the bobbin is being rotated within it, the yarn passing from the usual guide-eye (not shown) to the bgbbin, traveling about the cap and passing across its lower end to the bobbin, in the usual manner.

By employing an independent sleeve, 25, between the whirl b and the dead-spindle B I am enabled to not only keep the dead-spindle stationary-that is, not raise and lower it-but I am also enabled to keep the whirls in the same vertical position, so that the said whirls do not rise and fall with the builderrail.

The rising and falling of the whirl with the builder-rail causes the bands extending from the whirls to the usual tin drum for driving semer twist, making it harder and softer at different` portions of the yarn.

The cams, to be described, for operating the different arms for imparting motion to the bars carrying the clamps or jaws are somewhat Vmodified from the construction shown in my said application. v

Referring to the drawings, the rockshaft e6,

Acommon to my said application, has, as herein shown, fast upon it au arm,f, provided with a roller'or other stud, f', the said arm and stud being substantially as in my saidvapplication.

rIhe arm f has fastened to it at 34 a second arm, g Q',which supports a bar, g3, on which are mounted the clamps or jaws g4, adapted to hold and apply the empty bobbin d4 to the dead-spindle B3, and thence down upon the bobbin-driving tube. The shaft e6 has a rising-and-falling motion imparted to it by the rising and falling of the rack e, as in my said application, and as the rod rises the roller or other stud, f', travels in the 4straight part of the irregular groove f2 of the cam-plate'f3, starting from the bottom thereof and rising in a straight line to substantially the top thereof, in the position indicated in Figq;`

but when the shaft e6 is lowered then the roller-stud f', arrested by the switch 36, is made to travel about the branch groove 37, as in Fig. 7, and down again into the bottom of the groovef, a switch, 38, located at the bottom of the branch groove, preventing the roller-stud f,when rising, from entering the .lower end of the branch groove 37.

Thedetail Fig. 6 is intended to represent the bobbin-holding jaws g4 as in their uppermost position,with an empty bobbin, d, ready to loe applied to the dead-spindle as the shaft e is lowered,the clampg4 at such time being moved to the right (see Fig. 7) in position to place the hole in the bobbin d* immediately above the top of the spindle B3. The detail Fig. 6 also shows the jaws h6, to grasp and remove the filled bobbin fb, Fig. 4 showing more fully the arms carrying them, both iigures showing a full bobbin in the clamp. When the shaft e is elevated,the jaws h6 are moved in toward and made to grasp the full bobbinfb and remove it from the tube 31 and spindle; but prior to that the cap-clamping jaws t(best shown in Fig. 8) rise or are moved by or through the parts carrying them, to be described, and made to grasp the cap 33 and lift it from the spind1e.` The cam-platesf3,h, andw are all iixed,respectively, to stands 40,41, and 42, erected upon suitable extension plates, as 43, secured to the rail A. The cam-plate h has a straight groove, 16, and a branch groove, 162k, the said groove 16 being crossed bya switch,48,the branch groove being crossed.- bya switch, 49. The groove 16, as the rod es IOO starts to rise, receives in it the roller or other stud 15, extended from one side of an arm, h, loose on the said rod, the said arm It having attached to it an adjustable two-part arm, 71,2, provided with a bar it, upon which is mounted the series of clamps or jaws h6, which seize the full bobbin and remove it from the tube and spindle after or as the cap 83 is being removed by the jaws t. The roller or other stud 15 in the rise of the rod e6 starts from the bottom of the groove 16, meets the switch 48, and is thereby thrown into the branch groove 16*, such movement of the arm h throwing quickly forward the clamps orjaws it to grasp the full bobbin f b, as in Fig. 4, andas the roller or other stud 15 travcls upward in the said branch groove 16* (see Fig. 4) the clamps or jaws h rise vertically,yet holding the bobbin f b, and carry it np from the top of the spindle, and as soon as the full bobbin is lifted from the top of the spindle the roller-stud 15 comes into the upper diagonal portion of the branch groove 16* and throws the clamps orjaws h back into the position shown in Fig. 6, at one side of the top of the spindle. The cam to has an irregular groove composed of a straight part, 50, an inclined part, 51, another straight part, 52, an inclined part,.53, and a third long straight part, 54. The shaft e has loose upon it an arm, w', having a roller or other stud, fw?, which, when the shaft es commences to rise, rests in the bottom of the straight slot 50.

The arm w has fast to it an extension-arm, w, (see Fig. 8,) provided with a prolongation, w, which is jointed to the part w, the extension @o5 supporting a bar, w, extended throughout the length of the machine, which bar serves as a support for a series of clamps orjaws, t, which are made to grasp the cap 33 and lift it from the top of the spindle from the position Fig. S into the position Fig. 6, Fig. 7 showing the said cap on its downward passage to be put upon the top of the spindle, the jaws being, however, omitted. As shown in Fig. 8, the roller or other stud tu2 has risen through the branch part 5l, which moves the clamp orjaw t forward to grasp the cap, and there after, while the said roller or other stud continues to rise in the slot 52, the cap 33 is'lifted in a straight line, but as soon as the roller or other stud enters the groove 53 thejaw t and cap are thrown back quickly to the left, and thereafter, as the stud travels in the straight part 54, the clamps or jaws t, yet holding the cap, rise vertically.

All the jaws or clamps are composed of pairs of arms pivoted centrally, their rear ends being acted upon by suitable spiral or other springs, which act normally to close thejaws, the forward ends of the jaws being rounded, so that when they are pushed against the round surfaces of either the full bobbin, the empty bobbin, or the cap the said jaws will yield, and then close upon and grasp the parts within their jaws by a force measured by the said springs.

I have herein described my invention as applicable for spinning; but I desire it to be understood that my invention is equally well adapted for twisting together two or more yarns. v
